2023-08-22Support setting V-env LFSR bits with a compiler flag (#43)HEADmasterJerry Zhao1-2/+6
This makes it easier to support tests with large memory footprints, as the default 63 pages may be insufficient
2023-03-16Cope with presence of Smrnmi extensionAndrew Waterman2-0/+10
Enable RNMIs if the extension is present, as the feature affects trap behavior when RNMIs are masked.
2023-03-16Update encoding.h for Smrnmi definitionsAndrew Waterman1-1911/+4092
2023-03-03Increase v env stack sizeAndrew Waterman1-1/+1

2023-02-02env: trap and page fault filter mechanism (#40)deepak04143-0/+27
Certain tests (particularly negative) may require a fault to occur. However in order to pass the tests, page fault and traps must return back to the tests. This patch add support for page fault and trap filtering in env. Signed-off-by: Deepak Gupta <debug@rivosinc.com>
2022-01-31Reverse memcpy direction when evicts a page. (#34)eistar1-1/+1
In "evict" function in v/vm.c, when evict a dirty page in user space, memcpy should be from that page, rather than to evicted page.
2021-09-24update riscv_arch.h to support QEMU (#31)liweiwei901-2/+3
* update riscv_arch.h to support QEMU: add size attribute for tohost/fromhost add writing zero to (tohost + 4) to write_tohost * revert the align of tohost/fromhost to 64 bytes

Minor clang-related fixes
2020-11-24v/entry.S: replace sbadaddr with stvalGokturk Yuksek1-1/+1
The RISC-V Privileged ISA v1.10 uses stval instead of sbadaddr. Although GCC can cope with sbadaddr, clang cannot. It fails with: error: operand must be a valid system register name or an integer in the range [0, 4095]
2020-11-24Replace sptbr with satp throughoutGokturk Yuksek2-4/+4
The RISC-V Privileged ISA v1.10 uses satp instead of sptbr. Although GCC can cope with sptbr, clang cannot. It fails with: error: operand must be a valid system register name or an integer in the range [0, 4095] Modified the variable name in vm.c as well to ensure consistency and avoid possible confusion.
